when you get the super shotgun, the normal shotgun becomes a weapon for sniping far enemies. Basically:
>chainsaw: worthless
>berserk: good, but hit detection depends on the source port, GZDoom has great detection so you can punch cacos and mancubi
>pistol: worthless
>shotgun: sniping, killing straggler imps, saving ammo
>super shotgun: mid-short distance workhorse main weapon
>chaingun: sniping, stunlocking, killing stragglers
>rockets: great for medium enemies if you can afford it and have the distance
>plasma: OH SHIT button, can kill cyberdemons too
>bfg: slaughter weapon, quick baron or pain elemental kills, boss killer (2 shot cybies, 1 shot spiderdemons at close range)
